Download Torque and potential energy

Torque
Is the tendency of a force to
rotate an object about an axis,
fulcrum, or pivot
Torque = the force applied, the
length of the lever arm connecting
the axis to the point of force
application, and the angle
between the force vector and the
lever arm
In a golf context……
This works with the extension of
the arm in the golf. The more the
arm is extended, the greater the
length of the moment arm and
the lever, which in turn puts more
acceleration on the club head and
more power on the ball.

In the golf the rotation of the arm,
the club, the torso and the legs,
create torque. This torque
contributes to the angular velocity
of the club head, which creates
the acceleration on the ball and
has a dramatic effect on the force
emitted on the ball.
Gravitational Potential Energy
is energy an object possesses
because of its position in a
gravitational field.
We can use this in many sports to
create more energy and apply that to
an object.
In the backswing the golf club is
creating gravitational potential
energy as it lifts back against gravity
and is then released and aided by
gravity on the down swing.
In a golf context…..
As a club gets lighter (ie a wood is
lighter than a short iron), the
backswing should get slightly
longer. This is because as the
weight of the longer (wood) club
is the least, it needs to climb a
little higher in order to be pulled
down effectively by gravity.
